Z all whom; it may concern:

Be it known that we, JAMES WILDMAN and WILLIAM WILDMAN, citizens of the United States of America, residing at Chicago, inthe county of Cook and State of'Illinois, have invented certain newand useful Improvements in Smoke-Consumers, of which the following is a specification.

Our invention relates to certain new and useful improvements in smoke-consumers; and its object is to provide a small and compact device of this sort which shall combine with perfection of operation si mplicity,cheapness, and compactness. To these ends our invention consists in certain novel features of construction not heretofore known or used, which are fully illustrated in the accompanying drawings and described in this specification.

In the aforesaid drawingsFigure 1 is a section through a fire-box having our improved smoke-consurner in place, the boiler of the structure being shown in elevation. Fig. 2 is a horizontal section in the line 2 2 of Fig. 1. Fig. 3 is acentral horizontal section through the smoke-consumer, taken in the broken line 33 of Fig.4. Fig. 4 is an elevation of the smokeconsumer looking toward the front of the fire-boxthat is, looking to the left inFig. 1 from the inside; and Fig. 5 is a section in the line ofFig. 4.

Referring to the drawings, A is a boiler of the usual type, supported by suitable walls B. A suitable grate O is supported between the front wall B and. a short vertical wall B This is an ordinary'boiler construction, and

it will be understood, of course, that any form may be used. Ahollow drum D is supported in the front of the fire-box. This drum is barrel-shaped, as'is clearly indicated in Figs. 3 and 4.. Across this drum runs a vertical partition D, extending part way across the hollow ofthe drum, Fig. 5, and this partitionis provided with a series of longitudinal corrugations d, the purpose of which 1 will presently be explained. The drum D is supported by three pipes E, E, and F, respectively, which run through the front wall of the fire-box to a suitable casing G. A steam-pipe H runs from the boiler or other suitable source of steam-pressure and enters the casing G. The pipe II after entering Serial No. 115.394. (No model.)

said casing G gives olf three branches, one of them being the pipe F, heretofore referred to, which runs through the wall of the firebox and directly into the .dru m D. The other two branches of the pipe are designated by h h, and these pipes extend a short distance into thepipes E. Immediatelybehind the pipe E in the casing G are funnel-shaped openingsgg, so that steam passing out of the pipes h it will set up an'injector action and draw air with it from the funnel-shaped openings g 9 through the pipes E E.' The pipes E-extend directly through the drum D, being turned toward one another and extending to difierent elevations, as shown in Figs. 4 and 5. The side of the drum D farthest removed from the front of the fire-box is pierced by two rows of holes I and I, respectively. The holes I run at an angle to the holes I, but in a plane parallel to the plane of said openings.

The operation of the device will now be apparent, Steam passes down the pipe H and through the pipes F and h h. The steam which passes through the pipes h 7?. draws in a large volume of air and shootsit out through the pipes E, two jets of steam and air thus passing out in difierent parallel planes and at different angles, as indicated by the dark -sprays in Fig. The air becomes greatly heated in passing through the pipes E E, which aids in the perfect operation of. the device. The steam which passes through the pipe F strikes the corrugated diaphragm D, and any water which may be in it is separated out by the corrugations and is revaporized and superheated by the intense heatat which the drum is kept. This superheated steam then passes on, fills the drum, and shoots out through the perforations I I, forming two sprays of steam in different parallel planes,

one extending to the left and one to the right of the drum D and the two together forming a halfcircle of steam-spray. This is clearly indicated by the lines in Fig. 2. The result of thus shooting the superheated steam across thesurface of the burning coal upon the grate O and over the gases which are arising from said coal is to burn the gases completely, all coal-dust and soot being entirely consumed. It will be noted that this is an extremely 001D- pact smoke-consumer and that the cost of of a suitable steam-nozzle adapted to discharge two parallel sheets of steam across said fire-box substantially parallel to said grate, the lines of flow of the steam in one of said planes crossing the lines of fiow of the other of said planes, substantially as described.

2. In a device of' the class described, the combination with a fire box and grate, of a suitable steam-nozzle adapted to discharge two parallel sheets of steam across said firebox and means for discharging a jet of air across said fire-box between said sheets of steam, substantially as described.

3. In a device of the class described, the combination with a firebox and grate, of a suitable steam-nozzle adapted to discharge two parallel sheets of steam across said firebox, and means for discharging two jets of air across said fire-box between said sheets of steam, substantially as described.

4. In a device of the class described, the combination with a fire box and grate, of a suitable steam-nozzle adapted to discharge two parallel sheets of steam across said firebox, and means for discharging two jets of air across said fire-box between said sheets of steam and at different elevations, substantially as described.

5. In a device of the class described, the combination with a hollow drum, of a steamno zzle entering said drum and a plurality of perforations in said drum opposite said steamnozzle, said perforations being arranged in two parallel planes at different elevations and extending in different directions with respect to said dru m, substantially as described.

6. In a device of the class described, the combination with a hollow drum having suitable perforations on one side thereof, of a steam-nozzle entering said drum on the side opposite said perforations, and a corrugated partition extending partially across said drum opposite said nozzle, substantially as described.

'7. In a device of the class described, the combination with a suitable hollow drum having a suitable entrance and exit for steam,

of a pipe running through said drum and means for forcing air through said pipe, substantially as described.

8. In a device of the class described, the combination with a hollow drum having a suitable entrance and exit for steam, of a pipe for a discharge of air running through said drum and ending adjacent to the exit for steam from said drum and suitable steam injector-pipes opening into said air-pipes and adapted to force air through them, substantially as described.

9. In a device of the class described, the combination with a hollow drum having a suitable entrance for steam, of means where,- by two parallel sheets of steam may be discharged from said drum, two air-pipes passing through said drum and ending between said jets of steam, and means for forcing air through said air-pipes and discharging it between said sheets of steam, substantially as described.

10. In a device of the class described, the combination with a fire-box, of a hollow drum supported in said fire-box and subjected toa high degree of heat, air-tubes extending through said drums and opening into the firebox, steam-nozzles entering said tubesand a steam-nozzle entering directly into the drum, said drum being provided with two sets of perforations, one immediately above and the other immediately below the plane of the airpipes, whereby steam on entering said drum will be superheated before passingout through the perforations and the air passing through the air-pipes will be greatly heated in its passage therethrough, substantially as described.

In witness whereof we have hereunto set our hands, at Chicago, in the county of Cook and State of Illinois, this 11th day of July, A. D. 1902.
